PALLET.

Application filed December 10, 1921. Serial No. 521,402.

T 0 all whom it 77mg concern:

Be it known that 1, JOHN Knox, a citizen of the United States, and resident of Stanhope, in the county of Sussex and State of New Jersey, have invented certain new and useful Improvements in Pallets, of which the following is a specification.

In pallets or cars used. for transporting material undergoing heat treatment (in ovens for containing material to be baked) such as sintering ores or making briquettes the grate bars or plates frequently require replacement by reason of the continual heating of the same. Means have been used for detachably retaining such bars or plates in the frames of pallets, but such means are liable to injury and deterioration by reason of the continued heat and corrosion that oc curs between the parts, making it diflicult and expensive to remove and replace said bars or plates.

The object of my invention is to provide simple and effectual means to detachably retain the grate bars or plates in pallets, and to permit ready removal of the retaining means and replacement thereof.

My invention comprises novel details of improvement that will be more fully hereinafter set forth, and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, where- 1n- Figure 1 is a side view of a pallet or car embodying my invention, and

Fig. 2 is an enlarged cross section of Fig. 1.

The pallet or car illustrated may be of any suitable or usual construction with regard to its frame 1 and supporting wheels 1. The grate bars or plates 5 extend transversely within the frame and rest thereon adjacent to the ends of the bars. The'ends' of said bars are provided with recesses 6 on their upper surfaces to receive the adjacent ends of pins 3 which pass through holes 7 the side walls of frame .1. The side walls of the frame have hubs 2 through which said holes extend, which hubs have transverse apertures Q communicating with the holes 7 adapted to receive pins 4L shown in the form of cotter pins, which pass through corresponding openings 3 in pins 3.

When the grate bars or plates 5 are to be applied to the pallet the appropriate pins 3 are removed. The bars are placed within the frame with the corresponding recesses 6 facing upwardly and registering with the adjacent holes 7, and the pins 3 are inserted through said holes with the inner ends of the pins received in the recesses 6. The pins a are then inserted through the apertures in the hubs and the openings in the pins 3 to retain the pins on frame 1.- The bars 5 can not be displaced in any direction since they rest upon frame 1, abutting at their ends against the sides of the frame, are held down by the pins 8 and are kept from shift ing edgewise along the pallet by the metal at the sides of said recesses. When the bars are to be replaced the pins 4: are removed, pins 3 are pushed outwardly and the bars may be lifted from the pallet.

An advantage of my invention is that the pins 3 have smooth surfaces so they will not be liable to rust in the holes of the frame to resist their removal, since the pins may be readily knocked out of the holes in the frame with a hammer in case the pins become corroded or burned in the holes.

My improvement affords simple and convenient means, at relatively low cost, for removably retaining the bars or plates in pallets without requiring screws in threaded holes, which screws are liable to become fast in the pallet and to break'during' efforts to remove them, entailing considerable expense for replacement.

Having now described my invention, what I claim is:

1. A pallet comprising a frame, bars detachably fitted to said frame and provided with recesses at their ends, pins detachably fitted to the frame to be received in the recesses of the bars, and means to detachably connect the pins with the frame.

2. A pallet comprising a frame, bars detachably fitted in the frame and provided with recesses at their ends, said frame having holes adjacent to the recesses of said bars, pins slidable in said holes to be received in said recesses, and means to detachably retain the pins on the frame.

8. A pallet comprising a frame, bars detachably fitted in the frame and provided with recesses at their ends, said frame having holes adjacent to the recesses of said bars, pins slidable in said holes to be reeeived in said recesses, said frame having hubs on the exterior provided With apertures, said pins having openings to register with the apertures of the hubs, and pins detachabiy fitted in said apertures and openings to rGlllOYlbh retain the first named pins. r

4. A pallet comprising a fraine having means to support bars transversely therein and having side Walls provided with lateral holes, said bars having recesses in their upper surfaces at their ends to register with said holes, pins slidable in said holes to be reeeivedin the said recesses of the bars, said frame and pins having registering apertures and openings, and pins in said apertures and openings detachabiy retaining the first named pins.

Signed at Stanhope in the county of Sussex and State of New Jersey, this'30th day of November, A. D. 1921.

JOHN KNOX.
